Hello Michael , I have a Lortone tumbler which is at least 10 years
old and it was not new when I bought it. It is a sturdy machine,
designed for rock tumbling I believe, and I can only say that is has
never stopped working for me. ( It is probably listening right now
and will break down next time I use it.) Steel shot, warm water and
a shot of liquid detergent gives a beautiful soft sheen to silver and
Ruth, in cold, wet, windy Nottingham in the UK.
